PHYS 200 Unit 2: Kinematics
Flashcards do conjunto (16)
- 1positionlocation of object at particular time
- 2point of referenceused to define the position of a body precisely
- 3distancemagnitude of displacement between two positions
- 4distance traveledtotal length of path traveled between two positions
- 5displacement-change in position of object
- ∆x= x_f - x_0 - 6average velocity-displacement divided by elapsed time
-v = ∆x/∆t
-vector - 7instantaneous velocityvelocity at specific instant
- 8instantaneous speed-distance traveled divided by elapsed time
-scalar - 9average acceleration-rate at which velocity changes
-a = ∆v/∆t
-vector - 10instantaneous accelerationacceleration at specific instant in time
- 11deceleration-acceleration in direction opposite to direction of velocity
-has opposite sign as velocity - 12negative acceleration-acceleration in negative direction
- 13Kinematic Equations Summary-x = x_0 + vt
-v = (v_0 + v)/2
-v = v_0 + at
-x = x_0 + v_0 t + 1/2 at^2
-v^2 = v_0^2 + 2a(x - x_0) - 14free-fallstate of movement that results from gravitational force only
- 15acceleration due to gravity (on Earth)g = 9.80 m/s^2
- 16Kinematic Equations in Free-Fall-v = v_0 - gt
-y = y_0 + v_0 t - 1/2 gt^2
-v^2 = v_0^2 - 2g(y - y_0)
